MrMimic is an interactive audio device for kids, designed to explain how audio goes from analogue to digital.
MrMimic listens to everything that goes on around him and displays that analogue input as a waveform. When a recording is made MrMimic waits patiently, then takes the audio recording on a journey from analogue to digital and back again. A recording starts playing back continuously as soon as it has been made. The playback does not stop until another recording is made.
While the recording is played back its journey from audio to digital is visualized. Looking at MrMimic you still see the analogue input on the left display. The middle display shows a snapshot of the audio’s binary representation and the right display a format more descriptive of the audio’s now digitalized form: a spectrum.
The user can slow down and speed up the playback, using a slider situated next to the record button. These changes are instantly visualized on the displays. MrMimic’s ear also hears the output and updates its analogue display accordingly – thereby completing the audio’s transformation from analogue to digital and back again.
MrMimic went from brief to concept to design to implementation in just four days. It was developed at the Copenhagen Institute of Interaction Design (ciid.dk) as part of a 2 week Physicial Computing Class, taught by Massimo Banzi, David A. Mellis and David Gauthier. The class focused on introducing different techniques used to prototype interactive artifacts using the Arduino platform.
